Note: I had to enter in 1.75 for my thickness because my model was incorrectly thicker than it should have been. But this should be 1.5”

Indicate block’s origin

Depending on your cad file:A) only has the object

B) also has wax block modeled

If (A) set Symmetrical margin of .2”

If (B) choose Fit to Material

Set depth of model to -0.05 so bit hits all of the wax surface smoothly

Play with slider so the cut plane position of the model is where you want

IX. Zeroing XYZ on ShopBot

•Navigate to Start → ShotBot3 software

•Click the yellow KeyPad button, this will open the keypad interface. You can use the keyboard arrows and the page up and page down keys to move the shop bot.

•Move the shopbot using the keyboard to a position where you can easily access

•Open the plastic cover case and Grab the two wrenches that should be near by

• To get the collar off the spindle, place the wrenches like the image below:

•Pull the wrenches away from each other to loosen the collar off the spindle

•Pull the wrench away from each other to loosen the collar off the spindle

•Unscrew rest using your fingers

•Insert the end bit into the collar. The tool that sticks out is the max depth that can drill into your piece

• While keeping the end bit steady inside the collar, carefully screwthe collar back onto the spindle using your finger. Tighten using thewrench but this time squeeze wrenches inward towards each other.

Wrench 1

Wrench 2

•Use the keyboard/keypad to position the shopbot end bit so that it straddles the left-side top-edge of your wax block

• In the Command Console of the ShopBot3 software,Navigate to [Z]ero → Zero [x] axis

•Position the shopbot end bit so that it now straddles the bottom-side top-edge of your wax block

•Navigate to [Z]ero → Zero [y] axis

• To zero the z-axis, Put the alligator clip onto the collar and Place the metal plate on top of the material.

•Navigate to [C]uts → C2 - Zero Z axis with Zzero plate

•Click ok. Note: the software will ALWAYS freeze on the first time.Quit the program and restart. No worries the X and Y axis are saved.Try to zero the Z axis again. The auto z-axis zeroing will slowly make the end bit touch the metal plate twice.
